Abstract

Abstract:

A new polyoxometalate compound, Ag₄H₃PTi₂W₁₀O₄₀·16H₂O(1), was synthesized with Keggin-type potassium dititanodecatungstophosphate and silver acetate as raw materials. The produet was characterized by thermogravimetric analysis(TGA), infrared spectrum(IR), and solid diffuse reflectance spectrum(DRS). Single crystal X-ray diffraction shows that {AgO₆} units in compound 1 bridge [H₃PTi₂W₁₀O₄₀]^4-, leading to the formation of a two-dimensional layer structure parallel to ab-plane. And the two-dimensional layer can be further extended to three-dimensional network structure. Besides, DRS analysis indicates that compound 1 can absorb visible light and may be an excellent photocatalytic material.

Key words: Keggin-type, Titanium-substituted tungstophosphate, Silver
